Parameters:
パラメータ:(hd_id3154760.7)

Number: Any numeric expression that specifies the power that you want to raise "e" to (the base of natural logarithms). The power must be for both single-precision numbers less than or equal to 88.02969 and double-precision numbers less than or equal to 709.782712893, since Office Basic returns an Overflow error for numbers exceeding these values.
Number: 「e」(自然対数の底) の指数を取る数値。指数の値は、単精度型の場合で 88.02969 以下、倍精度型の場合で 709.782712893 以下とする必要があり、これらの値を超過すると Office Basic はオーバーフローエラーを返します。(par_id3150793.8)
